Python libraries

Definition

Python libraries are collections of pre-written code that simplify programming tasks by providing reusable functions and methods for various applications. They enable developers to perform complex operations, such as numerical computations or data manipulation, without writing code from scratch, making it easier to implement advanced functionalities. This is especially beneficial in contexts like solving differential equations, where specific algorithms and methods can be employed directly from these libraries.
